I'm testing the smoke effect, and I only get 250 frames of simulation.
What I've done so far is change the scene end frame to 1000, and I changed the particle emission end to 1000. I've seen posting that say to change the cache end, but it's disabled/grayed-out so I can't. Any thoughts?

All help is appreciated. Either directions in the UI or python snipit would work.

...any other users find this behavior odd? setting an arbitrary end frame for an element that isn't the scene end frame? can you somehow write an expression to link them together?
